1 way could be at night time. You need to pay an electricity bill to have light at night.
Advantages of using heat-producing light bulbs include lower upfront cost and familiarity. Disadvantages include higher energy consumption, shorter lifespan, and potential fire hazards. Energy-efficient alternatives, such as LED bulbs, have higher upfront cost but offer longer lifespan, lower energy consumption, and reduced fire risk.
light energy
A light bulb converts electrical energy into light energy and heat energy.
Electrical energy is transformed into light energy in a light bulb. Chemical energy is transformed into mechanical energy in an engine. Solar energy is transformed into electrical energy in a solar panel. Wind energy is transformed into electrical energy in a wind turbine. Food energy is transformed into thermal energy by the body to maintain body temperature.
No.it uses energy sources (electrical energy to light up
One of the disadvantages of an automatic street light is that sometimes it does not turn off when it should. This results in wasted energy and added costs.
IT TAKES LOTS OF ENERGY -Rob Walters
There are no energy sources without disadvantages.
None. But it does convert 5 watts of electrical power (energy per unit time) into 5 watts of [light + thermal] power.
What are the advantages and disadvantages of wave energy
The disadvantages of heat are that if there is no solar energy, then there is no heat.
TV- Electrical energy to light and sound energy Radio and stereo - Electrical energy to sound energy Fan- electrical energy to mechanical energy Toaster - Electrical energy to heat energy Light bulb- Electrical energy to Light energy Battery or cell - Chemical energy to electrical energy

Five examples of energy transformation:television-electrical energy->light energy->sound energy->heat energycar-chemical energy->mechanical energy->sound energy->heat energylight bulb-electrical energy->light energy->heat energyrubber duck-kinetic energy->elastic energy->sound energymatch-chemical energy->light energy->heat energy
Efficiency=Useful energy output divided by the energy input. i.e. 100 J is the energy input and you get 5 J light energy from a lamp, the waste energy would be 5 J.
